Barometer "Western Germany" Very Old

This barometer is over 50 years old. Marked "Western Germany". In the Early 1950's the markings were "Western Germany" and the markings changed again in the mid 50's to 1980's to "West Germany".

It looks to be made of Mahogany,Brass and it has a beveled glass front with an enamel face.

CONDITION: WORKS GREAT, does have some scratches on the wood surface as shown in picture #2. and the top ring is missing, but I usually hang it from the adjusting hole in the back.
